Description

Power saving method and equipment for user equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a power saving method and device for a user equipment.

Background

When the user equipment is located in a basement or other places with poor wireless signal coverage, the coverage enhancement technology is needed to improve the wireless signal strength to communicate with other equipment in a wireless communication network, so that the user equipment needs to transmit wireless signals to the other equipment or receive the wireless signals transmitted by the other equipment with higher power, the user equipment needs to consume more electric energy, the standby time or the time for the user equipment to transmit data is shorter, and the battery is usually supplied by the user equipment, so that the battery needs to be frequently replaced to facilitate the user equipment to have sufficient electric energy. The user device may be a Machine device (Machine to Machine, M2M) such as a sensor, an electric meter, a water meter, or an alarm.

In the prior art, the power of the ue may be saved by setting an IDLE Discontinuous Reception (IDLE DRX) cycle and an ACTIVE DRX (ACTIVE DRX) cycle of the ue. In the IDLE DRX cycle, since the ue does not establish Radio Resource Control (RRC) connection, the ue cannot transmit data with other devices, and mainly monitors Paging messages, i.e., Paging-DRX. The ACTIVE DRX cycle includes an ACTIVE period and a dormant period, the ue receives downlink data and control signaling using the receiver during the ACTIVE period of the ACTIVE DRX cycle, and turns off the receiver during the dormant period of the ACTIVE DRX cycle, that is, the DXR power saving mechanism is used to save power of the ue to extend the standby time of the ue or the time for transmitting data. Specifically, the ue establishes Radio Resource Control (RRC) connection with an evolved node b (eNB) in a connected state, and sends a DRX configuration parameter to the ue under Control of the eNB, and the ue calculates a DRX start time according to the DRX configuration parameter, so that the ue is periodically in an active period. And if the short DRX period is adopted, calculating the DRX starting time according to a System Frame Number (SFN), a subframe Number (subframe Number) and the short DRX period (short DRX-Cycle). And if the long DRX period is adopted, calculating the DRX starting time according to a System Frame Number (SFN), a subframe Number (subframe Number) and the long DRX period (long DRX-Cycle). Illustratively, as shown in fig. 1, one long DRX cycle is shown from time t1 to time t4, and the long DRX cycle includes an active period a and a sleep period b, as shown in fig. 2, one short DRX cycle is shown from time t1 to time t2, and three short DRX cycles are shown from time t1 to time t4, and each short DRX cycle includes an active period c and a sleep period d.

However, if the long DRX cycle is set to achieve the effect of ultra-long power saving and energy saving of the ue, the ue cannot use the receiver to receive downlink data and control signaling for a long time while in the sleep mode; if the short DRX period is set, the effect of ultra-long power saving and energy saving of the user equipment cannot be effectively realized. Therefore, how to improve the power saving efficiency of the ue while simplifying the complexity of the ue is an urgent problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a power saving method for a user equipment, as shown in fig. 3, including:

step 101, when User Equipment (UE) is in a connected state, acquiring power saving configuration parameters, wherein the power saving configuration parameters comprise a Discontinuous Reception (DRX) mode holding timer and a long sleep mode holding timer.

And 102, converting the DRX mode and the long sleep mode according to the power saving configuration parameters.

After obtaining the DRX mode holding timer and the long sleep mode holding timer included in the power saving configuration parameters, the user equipment is in a connected state, when the DRX mode holding timer configured in the power saving configuration parameters is overtime, the user equipment is transited to the long sleep mode, when the long sleep mode holding timer configured in the power saving configuration parameters is overtime, the user equipment is transited to the DRX mode, and the user equipment is operated according to the original DRX configuration parameters before the long sleep mode. Compared with the prior art that the power and energy saving of the user equipment are realized by setting the long DRX period and the short DRX period of the user equipment in a connection state of the user equipment, the long sleep mode can enable the user equipment to enter a sleep period for a longer time, and the user equipment returns to the DRX mode with the same period before the long sleep mode after the long sleep mode is finished, so that the behavior and state transition of the user equipment can be simplified, and the power saving efficiency of the user equipment is improved on the basis of simplifying the complexity of the user equipment.

An embodiment of the present invention provides a power saving method for a user equipment, as shown in fig. 4, including:

step 201, the ue obtains power saving configuration parameters.

Specifically, power saving configuration parameters are acquired from the broadcast message; or, acquiring power saving configuration parameters in static configuration in advance; or, acquiring a power saving configuration parameter from a Radio Resource Control (RRC) message; alternatively, the power saving configuration parameter is acquired from the MAC layer message.

It should be noted that the power saving configuration parameters include a Discontinuous Reception (DRX) mode holding timer, a long sleep mode holding timer, a DRX mode monitoring timer, an active mode holding timer, a DRX cycle, and a downlink control information interval (DCI interval).

Step 202, the ue transitions to the long sleep mode according to the power saving configuration parameters.

And the user equipment runs the DRX mode, and when the DRX mode holding timer is overtime, the user equipment jumps to the long sleep mode, and simultaneously starts the long sleep mode holding timer. Compared with the prior art, when the user equipment runs the long sleep mode, the user equipment does not need to monitor the scheduling information in the connection state, so that the electric energy of the user equipment is saved.

The long sleep mode is a mode in which the ue does not monitor a downlink control information scheduling assignment instruction in a connected state, and the long sleep mode holding timer is used to indicate a period in which the ue operates the long sleep mode. The DRX mode retention timer configured in the power saving configuration parameter expires including: and determining that the DRX mode holding timer is overtime when no random access information is sent and no scheduling information is received in the DRX mode holding timer, wherein the random access information is used for transmitting uplink data for the user equipment, and the scheduling information is used for transmitting the uplink data or the downlink data for the user equipment. The scheduling information may be a downlink control information scheduling assignment instruction DCI allocation.

It should be noted that the long sleep mode (long sleep mode) may also be referred to as a deep sleep mode, an Enhanced Unsynchronized State (EUS), or an enhanced power saving mode (ePSM).

Step 203, the ue transitions to the DRX mode according to the power saving configuration parameters.

The user equipment runs a long sleep mode, when the long sleep mode holding timer is overtime, the user equipment jumps to a DRX mode, and meanwhile, the DRX mode holding timer is started. Wherein the DRX mode holding timer is used for representing the time period of N DRX cycles, and N is a positive integer greater than or equal to 1. The timeout of the long sleep mode retention timer configured in the power saving configuration parameter comprises: and the random access information is not sent in the long sleep mode holding timer, and the long sleep mode holding timer is determined to be overtime.

Step 204, the user equipment sends random access information in the long sleep mode, and transitions to the active mode.

And the user equipment sends random access information in the long sleep mode to transmit uplink data, transitions to an active mode, stops the timeout of a long sleep mode holding timer, and starts the active mode holding timer, wherein the active mode holding timer is used for indicating the period of the user equipment running the active mode after running the DRX mode.

Step 205, the ue successfully demodulates the scheduling information in DRX mode, or sends the random access information, and transitions to active mode.

The user equipment successfully demodulates the scheduling information in the DRX mode, or sends the random access information to transmit uplink data or downlink data, and the user equipment successfully demodulates the scheduling information in a DRX mode monitoring timer, or sends the random access information in a DRX sleep period. Meanwhile, the DRX mode retention timer or the DRX mode monitoring timer is stopped, and the active mode retention timer is started. The DRX mode monitoring timer is used to indicate a period during which scheduling information is monitored for one DRX cycle.

Step 206, the ue transits to the DRX mode in the active mode according to the power saving configuration parameters.

And the user equipment transitions to the DRX mode when in the active mode, the data transmission is finished or the active mode holding timer is overtime, and simultaneously starts the DRX mode holding timer.

It should be noted that, when the user equipment monitors the scheduling information in the active mode, it is determined whether to start the active mode holding timer; if the activation mode holding timer is not started, starting the activation mode holding timer; and if the activation mode holding timer is started, restarting the activation mode holding timer.

Illustratively, as shown in fig. 5, a schematic diagram of a user equipment transition includes an active mode 11, a DRX mode 12, and a long sleep mode 13. When the user equipment is in a DRX mode, the user equipment does not send random access information and does not receive scheduling information in a DRX mode holding timer, the DRX mode holding timer is determined to be overtime, and the user equipment is transited to the long sleep mode, wherein the random access information is used for transmitting uplink data for the user equipment, and the scheduling information is used for transmitting the uplink data or downlink data for the user equipment. Successfully demodulating the scheduling information in a DRX mode monitoring timer, or transitioning to an active mode after sending the random access information in a DRX sleep period.

And when the user equipment is in the long sleep mode, the random access information is not sent in the long sleep mode holding timer, the long sleep mode holding timer is determined to be overtime, and the user equipment is transited to the DRX mode. And sending the random access information in a long sleep mode, and transitioning to the active mode.

When the user equipment is in an active mode, the data transmission is finished, the active mode keeps the overtime of a timer or receives a Media Access Control (MAC) layer command instruction to transition to the DRX mode; the DRX mode retention timer is set to 0 and transitions to the long sleep mode when an active mode retention timer times out or a MAC layer command indication is received.

Illustratively, another user equipment transition diagram is shown in fig. 6. t1 may indicate that the ue receives the implicit release timer during data transmission before the DRX mode is started, and when the implicit release timer expires, the ue determines that the time when the implicit release timer expires is the DRX initial starting value, and periodically wakes up to monitor the downlink control information according to the DRX cycle. t2 may indicate that if downlink control information is received within the DRX mode monitoring timer after DRX mode start, the active mode after DRX mode start is entered and the active mode maintaining timer is started. T3 may indicate that the user equipment is running into the DRX sleep period when the active mode retention timer times out. t4 may indicate that the DRX mode retention timer is started if it times out within the DRX mode monitoring timer. t5 may indicate that if the DRX mode retention timer times out, the user equipment is running long sleep mode and starts the deep sleep retention timer.

As shown in table 1, the definitions, start time, restart time, stop time, and timeout of the specifically defined active mode retention timer, DRX mode retention timer, long sleep mode retention timer, and DRX mode monitoring timer.

TABLE 1 timer definition Start-Up Table

After acquiring an active mode holding timer, a DRX mode holding timer and a long sleep mode holding timer which are included in power saving configuration parameters, when the DRX mode holding timer configured in the power saving configuration parameters is overtime, the user equipment is in a connected state, and transits to the long sleep mode, when the long sleep mode holding timer configured in the power saving configuration parameters is overtime, the user equipment transits to the DRX mode, and when the active mode holding timer is overtime, the user equipment transits to the DRX mode and operates according to the original DRX configuration parameters before the long sleep mode. Compared with the prior art that the power and energy saving of the user equipment are realized by setting the long DRX period and the short DRX period of the user equipment in a connection state of the user equipment, the long sleep mode can enable the user equipment to enter a sleep period for a longer time, and the user equipment returns to the DRX mode with the same period before the long sleep mode after the long sleep mode is finished, so that the behavior and state transition of the user equipment can be simplified, and the power saving efficiency of the user equipment is improved on the basis of simplifying the complexity of the user equipment.

An embodiment of the present invention provides a power saving method for a user equipment, as shown in fig. 7, including:

step 301, the user equipment UE determines a discontinuous reception DRX initial starting value.

Step 302, calculating a hyper frame number SFN for starting the DRX period according to the DRX period obtained by the power saving configuration parameters, the DRX initial starting value and the downlink control information interval DCI interval.

And 303, operating a DRX mode according to the SFN and the DRX initial starting value.

After acquiring an active mode holding timer, a DRX mode holding timer and a long sleep mode holding timer which are included in power saving configuration parameters, when the user equipment is in a connected state, a hyper-SFN started by the DRX cycle is calculated according to the DRX cycle, a DRX initial starting value and DCI interval, and when the DRX mode is operated according to the power saving configuration parameters, the DRX cycle is periodically started, so that the user equipment is in transition among the DRX mode, the long sleep mode and the active mode. Compared with the prior art that the power and energy saving of the user equipment are realized by setting the long DRX period and the short DRX period of the user equipment in a connection state of the user equipment, the long sleep mode can enable the user equipment to enter a sleep period for a longer time, and the user equipment returns to the DRX mode with the same period before the long sleep mode after the long sleep mode is finished, so that the behavior and state transition of the user equipment can be simplified, and the power saving efficiency of the user equipment is improved on the basis of simplifying the complexity of the user equipment.

Specifically, the DRX initial start value may be obtained through a power saving configuration parameter; or, determining the overtime moment of the active mode keeping timer as the DRX initial starting value; or, determining a data transmission end time before the DRX mode is started as the DRX initial start value, where the data transmission end time includes a time when an implicit release timer expires, a time when a Media Access Control (MAC) layer command is received, or a window when data transmission ends.

It should be noted that the configuration value field for configuring the DRX initial start value is 0 to ceil (a/B) -1, where a is the length of a Super frame (the length of the Super frame), and B is the downlink control information interval (DCI interval). Wherein, a slot (slot) is the minimum time unit, and each slot is 10 ms; one frame (frames) contains 8 slots, so the unit of each frame is 80 ms; one superframe (Super Frame) contains 64 frames, so the unit of each superframe is 5120 ms. As shown in fig. 8, 65536 superframes are included, one superframe includes 64 frames, and one frame includes 8 slots. The downlink control information interval (DCI interval) is a time length between downlink control information allocations (DCI allocation), and is configured by system information, and the time length thereof may refer to table 2, and the length of the downlink control information interval is increased, and may be any one of 1 frame, 2 frames, and 256 superframes.

Table 2 downlink control information interval

For example, when the length of the downlink control information interval is 1 frame, the configuration value range is 0 to ceil (a/B) -1, i.e., from 0 to 63; when the length of the downlink control information interval is 2, the configuration value range is 0 to ceil (A/B) -1, namely from 0 to 31; when the length of the downlink control information interval is 4, the configuration value range is 0 to ceil (A/B) -1, namely from 0 to 15; when the length of the downlink control information interval is 8, the configuration value range is 0 to ceil (A/B) -1, namely 0 to 7; when the length of the downlink control information interval is 16, the configuration value range is 0 to ceil (A/B) -1, namely from 0 to 3; when the length of the downlink control information interval is 32, the configuration value range is 0 to ceil (A/B) -1, namely from 0 to 1; when the length of the downlink control information interval is any one of 1 superframe to 256 superframes, the configuration value range is 0 to ceil (a/B) -1, i.e., from 0 to 0, i.e., only 0 can be configured. The ceil represents the smallest integer that returns a value greater than or equal to the specified expression.

Further, the DRX initial start value (drxStartOffset) of the DRX cycle is a parameter corresponding to a downlink control information interval (DCI interval), and the user equipment acquires, according to its own downlink control information interval (DCI interval), a DRX initial start time corresponding to the downlink control information interval. The calculating the hyper frame number SFN started by the DRX period according to the DRX period acquired by the power-saving configuration parameters, the DRX initial starting value and the downlink control information interval DCI interval comprises the following steps: and calculating the SFN started by the DRX period according to the sum of the downlink control information interval accumulated before the hyper-frame number corresponding to the DRX initial starting value and the downlink control information interval of the hyper-frame number corresponding to the DRX initial starting value and the DRX initial starting value. Wherein, the number of downlink control information intervals (DCI intervals) accumulated before the superframe number corresponding to the DRX initial starting time (drxStartOffset) is equal to the unit of converting the current SFN into the scheduling cycle from the superframe unit.

wherein, a is the length of a Super frame (the length of Super frame), B is a downlink control information interval (DCI interval), C is a DRX cycle, and D is the DRX initial start value.

wherein, B is a downlink control information interval, C is a DRX cycle, D is the DRX initial starting value, and floor represents taking a maximum integer no greater than an expression.

For example, if B is 4 frames, C is 8 downlink control information intervals, and D is 7. Since B is less than one superframe, the first formula employed calculates the DRX cycle initiated superframe number SFN. Namely, it is

A sequence of SFNs 7, 15, 23, 31, 39, etc. can be obtained. So that the user equipment periodically monitors the scheduling information after the closest SFN at the current transmission time. For example, if the SFN of the current transmission time is closest to 15, the ue wakes up periodically at the 7 th DCI interval of SFN 15, 23, 31, 39.

For example, if B is 2 superframes, C is 8 downlink control information intervals, and D is 0. Since B is greater than one superframe, the second formula is adopted: and calculating the hyper frame number SFN started by the DRX period. Namely, it is

Such a SFN sequence of SFN 0, 16, 32, 64, etc. can be obtained. The user equipment wakes up periodically after the closest SFN to the current transmission time instant. For example, if the SFN of the current transmission time is closest to 32, the user equipment periodically wakes up at 0 th DCI interval of SFN 32, 64, etc.

For example, as shown in fig. 9, the ue obtains the DRX initial start value according to a power saving configuration parameter, or determines the DRX initial start value at a time when an active mode keeping timer expires; or, periodically monitoring scheduling information at t1, t2, t3, t4, t5 for the DRX initial starting value and the DRX period determined at the time when the implicit release timer expires before the DRX mode is started, the time when a Media Access Control (MAC) layer command is received, or the end time of a data transmission window. As shown in fig. 10, the ue obtains the DRX initial start value according to the power saving configuration parameter, or the DRX initial start value determined at the time when the active mode retention timer expires; or, periodically monitoring scheduling information at t1, t2, t3, t4, t5 for the DRX initial starting value and the DRX period determined at the time when the implicit release timer expires before the DRX mode is started, the time when a Media Access Control (MAC) layer command is received, or the end time of a data transmission window.
